From Bulbapedia, the community-driven Pokémon encyclopedia.
The lake guardians, sometimes referred to as the lake trio or the legendary pixies, is a term used to describe the legendary trio residing in the three lakes of Sinnoh: Uxie, Mesprit, and Azelf. They are meant to represent knowledge, emotion, and willpower, respectively. They are based off of the Imperial Regalia of Japan: the Yata no Kagami (wisdom), Yasakani no Magatama (benevolence), and Kusanagi (valor).
Unlike previous trios, all three of the lake trio are of a single type, the Template:Type2, though like the others, they share an ability: Levitate. According to legend, when Arceus created the universe it created Uxie, Mesprit, and Azelf, and therefore is believed to be their master. According to one of Azelf's Pokédex entries, all three of them were born from the same egg.
It is interesting to note that each of the members of the lake trio has one of the qualities of the Abrahamic God: Uxie is omniscient, Mesprit is omnipresent, and Azelf is omnipotent. They could also be equated to, respectively, the Greek/Roman deities of Athena/Minerva, Poseidon/Neptune, and Zeus/Jupiter. A parallel for the Trio rest within Norse Mythology. Odin along with his brothers Vili and Vé bestow upon Ask and Embala various corporeal and spiritual gifts similar to those the Trio represent. Odin gave soul and life; Vili gave wit (intelligence) and sense of touch; and Vé gave countenance (appearance, facial expression), speech, hearing, and sight. It should also be noted that parts of their name come from fantasy creatures, pixies, sprites and elves, respectively. The other parts of their names come from pronouns: you (Uxie), me (Mesprit), and us (Azelf).
The members of the lake trio are tied for the lightest legendary Pokémon, and, tied with Rotom, are second for the lightest of all Pokémon (after Gastly and Haunter).

In the anime
All three first appeared in forms similar to souls. Mesprit appeared to Dawn during the start of her journey in Following a Maiden's Voyage!, Azelf appeared to Ash during the duration of the Wallace Cup in Pruning a Passel of Pals! and Uxie appeared to Brock while he was looking for a berry in Uncrushing Defeat!. Due to these encounters, all three established a connection to the human they each met.
They appeared in their physical forms for the first time in DP151, wherein, after being hired by Team Galactic, J was able to capture all three of them. Team Galactic was then able to control them using red gems. With their power, Cyrus was able to summon Dialga and Palkia during the next episode.
When the gems were broken by Pikachu, Piplup and Croagunk, the three were set free from Team Galactic's control. They then helped Ash and his friends stop the effects of summoning Dialga and Palkia.
